The following are some information on the maintenance responsibility of internal plumbing for consumers living in a private estate or building. If you live in a public housing estate, you should contact the management office who maintains all the estate internal plumbing.

Water distribution system

The Water Authority maintains the water supply distribution system up to the building or lot boundaries of the consumers.

Water mains & other associated water supply facilities

Whereas the management office or the registered agent maintains the water mains and other associated water supply facilities in the streets and communal areas within private housing estates.

Internal & communal plumbing within a building

Within a building, the individual consumers maintain the internal plumbing system serving their own flats. And the management office or the registered agent of a building maintains the communal part of the pipework system within the building. This includes water pumps, water tanks, communal piping and other associated communal installations.

Water meters

The Water Authority installs the water meters but the consumers have to be responsible for the safe custody of the individual meters serving their premises.

Many common water supply problems are caused by the lack of proper maintenance of the internal plumbing by the consumers, the management office or the registered agent. For example, poorly maintained water pumps often lead to disruption of supply, while corrosion in water pipes might cause discoloured water or even chokage and lead to weak supply pressure. Regular checking of the plumbing system can identify and rectify small defects before they develop into major problems.
